Exempel på hur man kan använda DIAMINES i en mening

• Kapton E is a mix of two dianhydrides, PMDA and biphenyltetracarboxylic acid dianhydride (BPDA), and two diamines, ODA and p-phenylenediamine (PPD).
• Then, these diamines are treated with phosgene to form a mixture of isocyanates, the isomer ratio being determined by the isomeric composition of the diamine.
• Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides.
• Scent compounds of carrion flowers responsible for their odour include diamines (putrescine and cadaverine), sulfur compounds and various phenolic molecules.
• This conversion is widely applicable for amines and alcohols, as well as aminoalcohols, diols, and diamines.
• The polymer is of particularly used for concentration of high boiling compounds such as alcohols, polyethylene glycols, diols, phenols, monoamines and diamines, ethanolamines, amides, aldehydes, ketones and chlorinated aromatics.
• The formation of these pigments involves the reaction of doubly diazotized aromatic diamines (derivatives of benzidine) with acetoacetanilides.
• Later, organic chemists have used the reaction as a general method of organic synthesis for highly hindered or bulky morpholinones or piperazinones from ketones (particularly acetone) and either β-amino alcohols or diamines.
• The diamines are not polar enough to dissolve in water, making interfacial polycondensation methods challenging; there has been success from 4’,4” -diphenyl phthalide dicarboxylic chloride and aliphatic diamines as the two phases of the solutions in where the polycondensation can occur at their interface.
• Tetramethylurea is suitable as a reaction medium for the polymerization of aromatic diacid chlorides (such as isophthalic acid) and aromatic diamines (such as 1,3-diaminobenzene (m-phenylenediamine)) to aramids such as poly (m-phenylene isophthalamide) (Nomex®).
• After several failures, the group completed a systematic study of potential polyamides by combining diamines with a similar series of diacids.
• The derived chiral imine is used to prepare enantiopure α-trifluoromethyl alanines and diamines by a Strecker reaction followed by either nitrile hydrolysis or reduction.
• The mechanical properties of the PUU largely depend on the specific diisocyanates, long-chain polyols, and short-chain diamines in play, because how these components interact determines how well the soft and hard segments of the elastomers both crystallize and undergo microphase separation.
